  guess what sector my new job is 

  .........yup - the lettings industry. 
 Not been involved in 'setting on' for baliffs, but can get you all the legal gumph tomorrow about it if you wish
 
  its a flipping nightmate dealing with absent landlords tho, I can tell you

  and tenants who wont let certification (for gas certs etc) take place - and then get the a r s e with us for getting eviction orders on them.
 They really think its just 'fun' to ignore letters - and dont understand the implications & penalies for the properties not having GSC's. 
 Anyways, rambling on - try some of TWPD's suggestions - particularly NEVER let a baliff in, unless a copper is present.
